Removing a Side Cover

Figure 5-6 Side Cover Removal Detail

Step 1. Loosen the blue rear retaining screw that secures the cover to the chassis.

NOTE Retaining screws are located at two different positions on the rear of the system:

a. At the top for the left side cover (facing the rear) and,

b. At the bottom for the right side cover (facing the rear).

This configuration allows the side covers to fit on either side.

CAUTION An intrusion switch is located on the chassis side at the front, directly behind and

under the side panel. Pull the cover out just far enough to clear the lip, then angle it

away from the chassis side to ensure that the cover does not snag the switch when

you remove it.

Failure to clear the intrusion switch with the side cover may break it, thereby

breaking the electrical circuit that allows the SEU to operate.
